Description

Ein- oder mehrphasiger Drei- oder mehrwicklungstransformator zum Speisen mehrerer Netze verschiedener Spannung Die Erfindung bezieht sich auf :ein- oder mehrphasige Drei- oder Mehrwicklungstransformatoren zur Speisung von Freileitungen und Verteilernetzen verschiedener Spannung von einer Energiequelle aus. Wird hierbei für die Umformung der Speisespannung auf die Übertragungsspannungen in üblicher Weise z. B. ein. Dreiwicklungstransformator mit konzentrisch übereinandergelagerten Wicklungen verwendet, so ergibt sich der Nachteil, daß die Reaktanz zweier der drei Wicklungen entweder sehr klein ist, und so die Kurzschlußsicherheit gefährdet wird, oder aber sehr groß ist und damit einen unerwünscht hohen Spannungsabfall zur Folge hat. Zur Vermeidung dieses Nachteils könnte man z. B. eine der Wicklungen in zwei Hälften zerlegen, so daß auf diese Weise vier konzentrische Wicklungen vorhanden sind. Damit wird aber die Berechnung des Transformators sehr erschwert und seine Herstellung umständlicher und teurer, wozu außerdem noch ein größerer Raumbedarf hinzukommt.Single or multi-phase, three or more winding transformer for feeding several networks of different voltage The invention relates to: one or multi-phase three or multi-winding transformers for feeding overhead lines and distribution networks of different voltages from one energy source. Will here for converting the supply voltage to the transmission voltages in the usual way Way z. B. a. Three-winding transformer with concentrically superimposed Windings are used, there is the disadvantage that the reactance of two of the three Windings is either very small, and so the short-circuit safety is endangered, or is very large and thus results in an undesirably high voltage drop Has. To avoid this disadvantage you could, for. B. one of the windings in two Separate the halves so that there are four concentric windings are. But this makes the calculation of the transformer very difficult and his Manufacture more complicated and expensive, including a larger space requirement come in addition.

Gemäß der Erfindung werden alle diese Mängel dadurch beseitigt, daß mindestens zwei Wicklungen in axialer Richtung in mindestens zwei Teile zerlegt sind, und daß die Wicklungsteile verschiedenen Durchmessers überkreuzt in Reihe geschaltet sind.According to the invention, all of these deficiencies are eliminated in that at least two windings split into at least two parts in the axial direction are, and that the winding parts of different diameters crossed in series are switched.

In der Zeichnung ist :als Ausführungsbelspiel der Erfindung in Abb. i und z in Aufriß und Grundriß ;ein Transformator mit konzentrischen Wicklungen dargestellt. Abb.3 zeigt einen solchen mit exzentrischen Wicklungen im Grundriß. In den Abbildungen bedeutet a die Oberspannungswicklung. Die Mittel- bzw, Unterspannungswicklungen sind in axialer Richtung in je zwei Hälften b1, b. und cl, e2 unterteilt, wobei die Wicklungshälften verschiedenen Durchmessers überkreuzt miteinander verbunden sind. Die Wicklungen b1, b2 und cl, c2 können dabei konzentrisch zum Kern d und zueinander liegen, wie in Abb. z dargestellt, oder aber exzentrisch zueinander, wie beispielsweise in Abb. 3 gezeigt, wobei es gleichgültig ist, welche der Wicklungen konzentrisch zum Kern liegt. Die überkreuzte Verbindung der Wicklungshälften von Wicklungen verschiedenen Durchmessers kann anstatt wie in Abb. i an gegeneinanderliegenden Wicklungsenden auch an in der Achsrichtung gleichliegenden Wicklungsenden vorgenommen werden, wobei die Wicklungen entgegengesetzten Wicklungssinn besitzen.The drawing shows: as an embodiment of the invention in Fig. i and z in elevation and plan; a transformer with concentric windings shown. Fig.3 shows one with eccentric windings in plan. In the figures, a means the high voltage winding. The medium or low voltage windings are in the axial direction in two halves b1, b. and cl, e2 subdivided, where the winding halves of different diameters are crossed together are. The windings b1, b2 and cl, c2 can be concentric to the core d and lie to each other, as shown in Fig.z, or eccentrically to each other, as shown for example in Fig. 3, it does not matter which of the windings is concentric to the core. The crossed connection of the winding halves of Windings of different diameters can be placed against each other instead of as in Fig Winding ends are also made at winding ends that are identical in the axial direction with the windings having opposite directions of winding.
